To keep peace throughout the world.
To develop friendly relations between nations.
To work together to help people live better lives, to eliminate poverty, disease and illiteracy in the world, to stop environmental destruction and to encourage respect for each other's rights and freedoms.
To be a centre fo
pollution. Dumping waste materials from human activity into rivers and streams is popular because the waste seems to disappear downstream. The main sources of water pollution are factory waste, oil and gas runoff from highways, and untreated human waste. When this waste dumped into rivers, the water downstream becomes undrinkable and unusable for agriculture, and also kills plant and animal life
pollution from raw sewage, industrial wastes, and agricultural runoff; limited natural freshwater resources; most of the population does not have access to potable water; deforestation; soil erosion; desertification

pollution, saline intrusion, etc.) The value of this criticality ratio that indicates high water stress is based on expert judgment and experience (Alcamo and others, 1999). It ranges between 20 % for basins with highly variable runoff and 60 % for temperate zone basins. In this map, we take an overall value of 40 % to indicate high water stress. We see that the situation is heterogeneous over th

-Interrupt emission of rainwater in retaining facility, as flow rate is enough by precipitation
2.Sedimentation of retaining facility
-The longer operating time is, the more sediment is piled up. So function is declined.
3.Non-point source
-Because rainwater isn’t pass the retaining facility and is inpoured, pollutions are expect.
